摘要

• While many people are fascinated by the brain, they can't really tell you that much about the properties about how the brain works because we don't teach neuroscience in schools.
  尽管很多人都对大脑十分着迷，他们却讲不出太多关于大脑的特征，以及它是怎样工作的，因为学校没有神经科学的课。

• And one of the reasons why is that the equipment is so complex and so expensive that it's really only done at major universities and large institutions.
  其中一个原因就是相应的设备太复杂又太昂贵，这些研究只有在高等学府 和大型研究机构才能进行。

• And that's a shame because one out of five of us, that's 20 percent of the entire world, will have a neurological disorder.
  很遗憾的是，我们每五个人当中就有一个，也就是全球人口的20%会受神经性失调的困扰。

• They're going to go down across your corpus callosum, down onto your spinal cord to your lower motor neuron out to your muscles here, and that electrical discharge is going to be picked up by these electrodes right here and we're going to be able to listen to exactly what your brain is going to be doing.
  这些信号会向下穿过胼胝体，进入你的脊髓，到达下运动神经元，再到达你这里的肌肉，这种电信号释放 会被这里的电极接收，于是我们就能够听到你的大脑到底想要做些什么。

• And so it turns out that there is a nerve that's right here that runs up here that innervates these three fingers, and it's close enough to the skin that we might be able to stimulate that so that what we can do is copy your brain signals going out to your hand and inject it into your hand, so that your hand will move when your brain tells your hand to move.
  实际上这里有一根神经一路上来并支配这三根手指的活动，而这根神经又离皮肤足够近，让我们能够 刺激它，所以我们能做的是复制从你(SK)的大脑向手臂发出的信号, 并把这个信号注入到你(MG)手臂里，于是你(MG)的手臂会在你(SK)的大脑告诉手臂要动的时候动。
